Description

Using nvm I tried running a "make check" and found that the style of buffer allocation used (i.e. "new Buffer(...) is deprecated in Node 10.  We need to switch according to the deprecation warning:
```
(node:28258) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.
```
